DETAILED DESCRIPTION

Various embodiments and aspects of the invention will be described with reference to details discussed below, and the accompanying drawings will illustrate the various embodiments. The following description and drawings are illustrative of the invention and are not to be construed as limiting the invention. Numerous specific details are described to provide a thorough understanding of various embodiments of the present invention. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present inventions.

Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in conjunction with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification do not necessarily all refer to the same embodiment.

Accordingly, embodiments of the invention provide a smart display device that deactivates a display of the smart display device based on a vision-based mechanism. Normally, smart display devices do not deactivate their displays as long as the smart display device is powered on. A smart display device will typically continuously display information on the display, regardless of whether or not a user is present. However, in some instances a user of a smart display device may desire for the display of the smart display device to be deactivated (e.g., turned off). For example, a user may wish reduce the power consumption of the smart display device by turning off the display. In another example, when a user leaves the house or goes to sleep they may wish to turn off the display. Accordingly, a user of the device may provide a voice command such as “screen off” or provide an input via a touchscreen of the smart display device that causes the display to deactivate. Such methods of deactivating the display of the smart display device are cumbersome, inefficient and may not be effective under certain circumstances.

Embodiments of the inventive system and methods provide a solution to this task by determining whether to deactivate a display of a smart display device based on a vision-based mechanism. A smart display device may include a light capture device, such as a camera, that can capture one or more images of the surroundings of the smart display device. For example, the camera may capture a video that includes a sequence of images of the environment in front of the smart display device. The light capture device provides the images to a display controller of the smart display device.

The display controller identifies one or more characteristics in the images received from the light capture device. Examples of characteristics that may be identified by the display controller include, but are not limited to, movement of objects within the images, the detection of a person (e.g., user) within the images, the distance of the person from the smart display device and the direction of the gaze of the person relative to the smart display device. The identified characteristics are provided to an algorithmic control module of the display controller for analysis. The algorithmic control module may include a machine learning model. The identified characteristics provided to the algorithmic control module may be provided as inputs into the machine learning model. The machine learning model may then utilize the identified characteristics to determine whether the display of the smart display device is to be deactivated.

Accordingly, by using identified characteristics of images captured by the light capture device in a machine learning model, the display controller of the smart display device may intelligently determine when to deactivate the display of the smart display device, reducing the power consumption of the smart display device. Furthermore, by intelligently determining when to deactivate the display of the smart display device, a user may no longer be required to provide a voice command or physical input to deactivate the display, improving the user experience of the smart display device.

FIG. 1 is a block diagram illustrating an example of a display controller of a smart display device 100 according to one embodiment. Referring to FIG. 1, smart display device 100 includes, but is not limited to, display controller 110 operatively coupled to a light capture device 105 and a display 150. Display controller 110 may be implemented in software, hardware, or a combination thereof. For example, at least some of the components of display controller 110 may be loaded into a memory (e.g., random access memory or RAM such as dynamic RAM or DRAM) and executed by processing logic of one or more processors (e.g., microprocessors such as central processing units or CPUs, or general-purpose processing units or GPUs) of smart display device 100 (not shown). Display 150 may be any type of display, such as a touch screen display, that is configured to receive signals from display controller 110 to activate and deactivate.

The light capture device 105 may be configured to capture incoming light as images and transmit signals corresponding to the captured light to the display controller 110. In embodiments, light capture device 105 may be a camera operatively coupled to the display controller 110. In embodiments, light capture device 105 may be a single camera. In some embodiments, light capture device 105 may be multiple cameras.

The display controller 110 may include a movement detection module 115. The movement detection module 115 may be configured to identify movement of objects in proximity of the smart display device 100. In embodiments, the movement detection module 115 may identify the movement of objects in images captured by light capture device 105. For example, the movement detection module 115 may identify an object within an image and compare sequential images to determine if the object has moved. In an embodiment, the movement detection module 115 may determine if the object has moved by calculating a pixel difference between two images. In embodiments, the movement detection module 115 may determine if the object has moved by tracking a contour of an object within images. In some embodiments, the movement detection module 115 may be operatively coupled to a sensor, such as a motion sensor, and determine whether an object has moved based on signals received from the sensor.

The display controller 110 may include a person detection module 120. The person detection module 120 may be configured to determine whether a person is present in an image. In embodiments, the person detection module 120 may output a contour box of a person within the image along with a confidence level that the contour box corresponds to a person in the image.

The display controller 110 may further include a depth calculation module 125. The depth calculation module 125 may be configured to determine the depth of an object in an image. The depth of the object may correspond to the distance between the object and the light capture device 105 of the smart display device 100. In some embodiments, the depth calculation module 125 may utilize multiple cameras to determine the depth of one or more objects within an image. For example, a first image captured by a first camera may be compared to a second image captured by a second camera at the same time to determine the depth of the object within the image. In embodiments including a single camera, the depth calculation module 125 may approximate an objects distance to the camera by determining a portion of the image occupied by the object. For example, if a person's face occupies 80% of an image, then the depth calculation module 125 may approximate that the person is in close proximity to the camera, given that the camera is not zoomed in.

The display controller 110 may include a gaze detection module 130. The gaze detection module 130 may be configured to detect whether a person in an image is looking at the light capture device 105 or the smart display device 100. In embodiments, the gaze detection module 130 may utilize one or more algorithms to detect the position of a person's eyes within an image. The gaze detection module 130 may then determine whether the person's eyes are looking in a direction towards the light capture device 105 or the smart display device 100.

In embodiments, the movement detection module 115, the person detection module 120, the depth calculation module 125 and/or the gaze detection module 130 can operate in parallel. In some embodiments, the movement detection module 115, the person detection module 120, the depth calculation module 125 and/or the gaze detection module 130 can operate in series. For example, the person detection module 120 may provide data to the depth calculation module 125 and the depth calculation module may provide data to the gaze detection module 130.

The display controller 110 may include a screen status module 140. The screen status module 140 may be configured to provide an output that indicates whether the display 150 is activated (e.g., turned on) or deactivated (e.g., turned off). The display controller 110 may further include an off time smoothing module 145. The off time smoothing module 145 may be configured to determine how frequently display 150 is activated and/or deactivated.

The display controller 110 may further include an algorithmic control module 135. The algorithmic control module 135 may receive data from movement detection module 115, person detection module 120, depth calculation module 125, gaze detection module 130, screen status module 140 and/or off time smoothing module 145. The algorithmic control module 135 may be configured to determine whether to activate or deactivate the display 150 of the smart display device 100 based on the received data. In embodiments, the algorithmic control module 135 may utilize a machine learning model to determine whether to activate or deactivate the display 150 and determine a confidence score. In an embodiment, the machine learning model may be received from a remote server, as will be discussed in further detail at FIG. 2. Examples of machine learning models that may be utilized by the algorithmic control module 135 include, but are not limited to, linear models, non-linear models, shallow models and deep models. Upon the algorithmic control module 135 determining that the display 150 is to be activated/deactivated, the display controller 110 may deactivate the display 150 based on the determination by transmitting a signal to the display 150.

FIG. 2 is a block diagram illustrating a network configuration 200 according to one embodiment. Referring to FIG. 2, network configuration 200 includes a smart display device 210 communicatively coupled to a server 220 over a network 240. Smart display device 210 may correspond to smart display device 100, as previously described at FIG. 1. Server 220 can be any server and may include one or more processing devices (not shown). Server 220 may be operatively coupled to a data store 230. The data store 230 may be a persistent storage that is capable of storing data. A persistent storage may be a local storage unit or a remote storage unit. Persistent storage may be a magnetic storage unit, optical storage unit, solid state storage unit, electronic storage units (main memory), or similar storage unit. Persistent storage may also be a monolithic/single device or a distributed set of devices. In embodiments, server 220 and data store 230 may be components of a cloud-based platform.

Network 240 may be a public network (e.g., the internet), a private network (e.g., a local area network (LAN) or wide area network (WAN)), or a combination thereof. In one embodiment, network 240 may include a wired or a wireless infrastructure, which may be provided by one or more wireless communications systems, such as a wireless fidelity (WiFi) hotspot connected with the network 240 and/or a wireless carrier system that can be implemented using various data processing equipment, communication towers (e.g. cell towers), etc.

Processing logic of the processing device of server 220 may be configured to train a machine learning model that is to be utilized by an algorithmic control module (e.g., algorithmic control module 135 of FIG. 1) of smart display device 210. Sample data not associated with the smart display device, such as previously acquired data from one or more different smart display devices, may be used as training sets for the machine learning model. The processing logic of server 220 may execute the machine learning model using the sample data and the outputs of the machine learning model may be analyzed to determine whether the machine learning model is functioning properly. After the machine learning model is trained by the processing logic, the machine learning model may be provided to the smart display device 210 via the network 240.

In some embodiments, upon receipt of the machine learning model, the algorithmic control module of smart display device 210 may utilize the machine learning model and characteristics associated with images captured by a light capture device to determine whether or not to activate/deactivate a display of the smart display device. It should be noted that, in embodiments, the determination is performed by processing logic of the smart display device 210 without providing the characteristics associated with the images to server 220 via the network 240 to protect the privacy of users of smart display device 210.

FIG. 3 is an illustration 300 of an example of characteristics provided to an algorithmic control module to determine whether to deactivate a display of a smart display device in accordance with embodiments. As previously described, characteristics associated with one or more images received from a light capture device may be identified and provided to an algorithmic control module 135. The algorithmic control module 135 may use the received characteristics as inputs to a machine learning model which may determine whether to deactivate display 150 of a smart display device. Each of the characteristics may influence the determination of the machine learning model on whether or not to deactivate display 150.

At block 305, a display controller may identify movement of objects in images, as previously described. The algorithmic control module 135 may utilize the movement of objects in images to determine whether or not to deactivate display 150. For example, if the movement of objects in the images is below a threshold amount, indicating minimal activity around the smart display device, the probability that the algorithmic control module 135 determines to deactivate display 150 may increase. In embodiments, the algorithmic control module 135 may identify period of time during the day in which there is minimal activity around the smart display device. For example, the algorithmic control module 135 may determine that between 8 AM-5 PM on Monday through Friday there is minimal activity around the smart display device. Accordingly, during the identified period of time, the probability that the algorithmic control module 135 determines to deactivate display 150 may increase.

At block 310, the display controller may identify a person in the images. The algorithmic control module 135 may utilize the presence of a person in images to determine whether or not to deactivate display 150. For example, if an object in the image is a person, indicating that the person may be using the smart display device, the probability that the algorithmic control module 135 determines to deactivate display 150 may decrease. However, if the object in the image is a cat, the probability that the algorithmic control module 135 determines to deactivate display 150 may increase. In embodiments, the algorithmic control module 135 may utilize movement data to verify that a person is in the images. For example, if a person identified in images has a static location (e.g., is not moving) for a period of time, the algorithmic control module 135 may determine that the person identified in the image is a photograph of a person. Accordingly, if the algorithmic control module 135 determines that a person identified in the image is not actually a person, then the algorithmic control module 135 may disregard the identified person when determining whether or not to deactivate the display 150.

At block 315, the display controller may identify the depth of the person in the images. The algorithmic control module 135 may utilize the depth of a person in images to determine whether or not to deactivate display 150. In embodiments, if the distance from a person in the image to the smart display device is below a threshold distance, the probability that the algorithmic control module 135 determines to deactivate the display 150 may decrease. For example, if a person is within a 5 foot threshold distance from the smart display device, indicating the person is likely using the smart display device, then the probability that the algorithmic control module 135 determines to deactivate the display may decrease. In some embodiments, if the distance from a person in the image to the smart display device exceeds a threshold distance, the probability that the algorithmic control module 135 determines to deactivate the display 150 may increase. For example, if the distance of a person to the smart display device is greater than a 20 foot threshold, the person likely could not see the information on the display of the smart display device and/or is likely not using the display of the smart display device. Accordingly, the probability that the algorithmic control module 135 determines to deactivate the display 150 may increase.

At block 320, the display controller may identify the gaze direction of the person in the images. The algorithmic control module 135 may utilize the gaze direction of a person in images to determine whether or not to deactivate display 150. For example, if the gaze direction of a person in the images is in a direction towards the smart display device, indicating the person is likely using the display 150 of the smart display device, then the probability that the algorithmic control module 135 determines to deactivate the display 150 may decrease. However, if the gaze direction of a person in the images is not in a direction towards the smart display device, indicating the person is not likely using the display 150 of the smart display device, then the probability that the algorithmic control module 135 determines to deactivate the display 150 may increase.

It should be noted that although illustration 300 includes identified characteristics at blocks 305, 310, 315 and 320 being utilized to determine whether or not to deactivate display 150, in embodiments more or less characteristics may be utilized to determine whether or not to deactivate display 150.

FIG. 4 is a flow diagram illustrating a process 400 of display off time smoothing according to one embodiment. Process 400 may be performed by processing logic which may include software, hardware, or a combination thereof. For example, one or more operations of process 400 may be performed by the off time smoothing module 145 of display controller 110 of FIG. 1.

Referring to FIG. 4, in operation 401, processing logic determines to deactivate a display of a smart display device based on identified characteristics of received images, as previously described. In operation 402, processing logic deactivates the display of the smart display device.

In operation 403, the processing logic determines if the display has been activated within a threshold amount of time of the deactivation of the display at operation 402. For example, the processing logic may determine if the display has been activated by a user within a five minute threshold amount of time since the deactivation of the display at operation 402. A user activating the display within the threshold amount of time may indicate that the processing logic determined to deactivate the display at an inappropriate time. Accordingly, to prevent deactivation of the display at an inappropriate time, at operation 404, if the display has been activated within the threshold amount of time, the processing logic determines to not subsequently deactivate the display. In embodiments, the processing logic may determine to not subsequently deactivate the display for a period of time. For example, the processing logic may determine to not subsequently deactivate the display for one hour.

If the display has not been activated within a threshold amount of time, at operation 405 the processing logic determines to subsequently deactivate the display. In some embodiments, data associated with the determinations as previously described in process 400 may be provided to the algorithmic control module 135. The data may be utilized by a machine learning model to determine whether or not to deactivate the display of the smart display device, as previously described.

FIG. 5 is a flow diagram illustrating a process 500 of determining to deactivate a display of a smart display device based on characteristics of an image according to one embodiment. Process 500 may be performed by processing logic which may include software, hardware, or a combination thereof. For example, process 500 may be performed by display controller 110 of FIG. 1. Referring to FIG. 5, in operation 501, processing logic receives an image from a light capture device. In operation 502, processing logic identifies characteristics of the image received from the light capture device. In operation 503, processing logic determines whether to deactivate a display of the smart display device based on the characteristics of the image. In response to determining to deactivate the display of the smart display device based on the characteristics of the image, in operation 504, processing logic deactivates the display of the smart display device.

FIG. 6 is a block diagram illustrating an example of a data processing system which may be used with one embodiment of the invention. For example, system 1500 may represent any of data processing systems described above performing any of the processes or methods described above, such as, for example, a client device or a server described above, such as, for example, smart display device 100 of FIG. 1 as described above.

System 1500 can include many different components. These components can be implemented as integrated circuits (ICs), portions thereof, discrete electronic devices, or other modules adapted to a circuit board such as a motherboard or add-in card of the computer system, or as components otherwise incorporated within a chassis of the computer system.

Note also that system 1500 is intended to show a high level view of many components of the computer system. However, it is to be understood that additional components may be present in certain implementations and furthermore, different arrangement of the components shown may occur in other implementations. System 1500 may represent a desktop, a laptop, a tablet, a server, a mobile phone, a media player, a personal digital assistant (PDA), a Smartwatch, a personal communicator, a gaming device, a network router or hub, a wireless access point (AP) or repeater, a set-top box, or a combination thereof. Further, while only a single machine or system is illustrated, the term “machine” or “system” shall also be taken to include any collection of machines or systems that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

In one embodiment, system 1500 includes processor 1501, memory 1503, and devices 1505-1508 via a bus or an interconnect 1510. Processor 1501 may represent a single processor or multiple processors with a single processor core or multiple processor cores included therein. Processor 1501 may represent one or more general-purpose processors such as a microprocessor, a central processing unit (CPU), or the like. More particularly, processor 1501 may be a complex instruction set computing (CISC) microprocessor, reduced instruction set computing (RISC) microprocessor, very long instruction word (VLIW) microprocessor, or processor implementing other instruction sets, or processors implementing a combination of instruction sets.

Processor 1501, which may be a low power multi-core processor socket such as an ultra-low voltage processor, may act as a main processing unit and central hub for communication with the various components of the system. Such processor can be implemented as a system on chip (SoC). Processor 1501 is configured to execute instructions for performing the operations and steps discussed herein. System 1500 may further include a graphics interface that communicates with optional graphics subsystem 1504, which may include a display controller, a graphics processor, and/or a display device.

Processor 1501 may communicate with memory 1503, which in one embodiment can be implemented via multiple memory devices to provide for a given amount of system memory. Memory 1503 may include one or more volatile storage (or memory) devices such as random access memory (RAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), static RAM (SRAM), or other types of storage devices. Memory 1503 may store information including sequences of instructions that are executed by processor 1501, or any other device. For example, executable code and/or data of a variety of operating systems, device drivers, firmware (e.g., input output basic system or BIOS), and/or applications can be loaded in memory 1503 and executed by processor 1501. An operating system can be any kind of operating systems, such as, for example, Windows® operating system from Microsoft®, Mac OS®/iOS® from Apple, Android® from Google®, Linux®, Unix®, or other real-time or embedded operating systems such as VxWorks.

System 1500 may further include IO devices such as devices 1505-1508, including network interface device(s) 1505, optional input device(s) 1506, and other optional IO device(s) 1507. Network interface device 1505 may include a wireless transceiver and/or a network interface card (NIC). The wireless transceiver may be a WiFi transceiver, an infrared transceiver, a Bluetooth transceiver, a WiMax transceiver, a wireless cellular telephony transceiver, a satellite transceiver (e.g., a global positioning system (GPS) transceiver), or other radio frequency (RF) transceivers, or a combination thereof. The NIC may be an Ethernet card.

Input device(s) 1506 may include a mouse, a touch pad, a touch sensitive screen (which may be integrated with display device 1504), a pointer device such as a stylus, and/or a keyboard (e.g., physical keyboard or a virtual keyboard displayed as part of a touch sensitive screen). For example, input device 1506 may include a touch screen controller coupled to a touch screen. The touch screen and touch screen controller can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen.

IO devices 1507 may include an audio device. An audio device may include a speaker and/or a microphone to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and/or telephony functions. Other IO devices 1507 may further include universal serial bus (USB) port(s), parallel port(s), serial port(s), a printer, a network interface, a bus bridge (e.g., a PCI-PCI bridge), sensor(s) (e.g., a motion sensor such as an accelerometer, gyroscope, a magnetometer, a light sensor, compass, a proximity sensor, etc.), or a combination thereof. Devices 1507 may further include an imaging processing subsystem (e.g., a camera), which may include an optical sensor, such as a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, utilized to facilitate camera functions, such as recording photographs and video clips. Certain sensors may be coupled to interconnect 1510 via a sensor hub (not shown), while other devices such as a keyboard or thermal sensor may be controlled by an embedded controller (not shown), dependent upon the specific configuration or design of system 1500.

To provide for persistent storage of information such as data, applications, one or more operating systems and so forth, a mass storage (not shown) may also couple to processor 1501. In various embodiments, to enable a thinner and lighter system design as well as to improve system responsiveness, this mass storage may be implemented via a solid state device (SSD). However in other embodiments, the mass storage may primarily be implemented using a hard disk drive (HDD) with a smaller amount of SSD storage to act as a SSD cache to enable non-volatile storage of context state and other such information during power down events so that a fast power up can occur on re-initiation of system activities. Also a flash device may be coupled to processor 1501, e.g., via a serial peripheral interface (SPI). This flash device may provide for non-volatile storage of system software, including a basic input/output software (BIOS) as well as other firmware of the system.

Storage device 1508 may include computer-accessible storage medium 1509 (also known as a machine-readable storage medium or a computer-readable medium) on which is stored one or more sets of instructions or software (e.g., module, unit, and/or logic 1528) embodying any one or more of the methodologies or functions described herein. Processing module/unit/logic 1528 may represent any of the components described above, such as, for example, display controller 110 as described above. Processing module/unit/logic 1528 may also reside, completely or at least partially, within memory 1503 and/or within processor 1501 during execution thereof by data processing system 1500, memory 1503 and processor 1501 also constituting machine-accessible storage media. Processing module/unit/logic 1528 may further be transmitted or received over a network via network interface device 1505.

Computer-readable storage medium 1509 may also be used to store the some software functionalities described above persistently. While computer-readable storage medium 1509 is shown in an exemplary embodiment to be a single medium, the term “computer-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The terms “computer-readable storage medium” shall also be taken to include any medium that is capable of storing or encoding a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present invention. The term “computer-readable storage medium” shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media, or any other non-transitory machine-readable medium.

Processing module/unit/logic 1528, components and other features described herein can be implemented as discrete hardware components or integrated in the functionality of hardware components such as ASICS, FPGAs, DSPs or similar devices. In addition, processing module/unit/logic 1528 can be implemented as firmware or functional circuitry within hardware devices. Further, processing module/unit/logic 1528 can be implemented in any combination hardware devices and software components.

Note that while system 1500 is illustrated with various components of a data processing system, it is not intended to represent any particular architecture or manner of interconnecting the components; as such details are not germane to embodiments of the present invention. It will also be appreciated that network computers, handheld computers, mobile phones, servers, and/or other data processing systems which have fewer components or perhaps more components may also be used with embodiments of the invention.

Some portions of the preceding detailed descriptions have been presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the ways used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussion, it is appreciated that throughout the description, discussions utilizing terms such as those set forth in the claims below, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

The techniques shown in the figures can be implemented using code and data stored and executed on one or more electronic devices. Such electronic devices store and communicate (internally and/or with other electronic devices over a network) code and data using computer-readable media, such as non-transitory computer-readable storage media (e.g., magnetic disks; optical disks; random access memory; read only memory; flash memory devices; phase-change memory) and transitory computer-readable transmission media (e.g., electrical, optical, acoustical or other form of propagated signals—such as carrier waves, infrared signals, digital signals).

The processes or methods depicted in the preceding figures may be performed by processing logic that comprises hardware (e.g. circuitry, dedicated logic, etc.), firmware, software (e.g., embodied on a non-transitory computer readable medium), or a combination of both. Although the processes or methods are described above in terms of some sequential operations, it should be appreciated that some of the operations described may be performed in a different order. Moreover, some operations may be performed in parallel rather than sequentially.

In the foregoing specification, embodiments of the invention have been described with reference to specific exemplary embodiments thereof. It will be evident that various modifications may be made thereto without departing from the broader spirit and scope of the invention as set forth in the following claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.
